Obesity impairs quality of life by causing various hazardous effects on respiratory functions of an individual along with other medical complications
The objective of the study was to evaluate effect of body fat percentage on PEFR in young adults of Indian population.120 students of 18–25 years age group who had no lung disease were recruited. Their age, sex, height, weight were recorded and BMI was calculated. Accordingly 60 students with BMI 25.0 -29.9 kg/m2 constituted study group and 60 students with BMI 18.5–24.9 kg/m2 constituted control group. Skinfold thickness was calculated using 4-site method (biceps, triceps, subscapular and suprailiac) with the help of Skinfold Caliper. Body fat percentage was calculated by using Durnin and Womersley method.
PEFR was recorded by computerised spirometry. The statistical analysis was done using appropriate tests.
The study group presented with lower values of PEFR than control group. Moreover PEFR was having strong negative correlation with body fat percentage. The effect of body fat percentage on PEFR indicates that independently obesity affects expiratory flow volume and pulmonary mechanics of an individual.
